Abstract

Method for controling fiber orientation of paper web W in the headbox of a paper machine. In the method extra streams Fin-Fout are guided on the two opposite edge parts of the flow channel of the headbox in the flow direction F that prevails in the headbox to edge passages 131-5; 26 at turbulence generators 12, 13 that precede its lip part 14, 15, 16. By controlling the magnitude and/or mutual ratio between the additional streams a cross-directed flow rate is generated in the lip stream from the headbox which compensates for oblique rotation of the fiber orientation. To control the thickness- directed (z-directed) orientation of the paper W being produced with the paper machine that is connected to the headbox the distribution F1/F2/F3/F4/F5 of said extra streams is controlled in layers in the thickness direction on the two edge regions of the headbox. Water and/or pulp suspension are used as extra streams. <IMAGE>
